Pollutant causes delayed flowering in plants
...own that stimuli, such as drought, salt stress and pathogen
infection, induced internal nitric oxide production. But it was not expected that external nitric oxide affected the flowering pathway." To explore how the molecular machinery of the plant was affected by nitric oxide, the researchers identified muta...
Scientists decipher genetic code of biothreat pathogen

that causes the horse disease: Burkholderia mallei.... The study found that B. mallei, a highly evolved pathogen
that has been deployed in the past as a biological weapon, has an extremely regulated set of virulen...

studied by the visiting scholars in the GID program is the African trypanosome. This vicious parasite causes human sleeping sickness, a fatal disease that has reemerged as a major health problem in sub-Saharan Africa. Gustave Simo, from Cameroon, wil...

invasion. To circumvent the immune system, a parasite has to either slip through the plant radar system or affect the cellular immune response following its detection. The mildew chose the latter strategy and therefore manipulates the so called MLO p...
Promising hospital anti-infection strategy probably won't work, study shows
...heory behind antibiotic cycling is that, just as a pathogen
strain begins to adapt to a particular antibiotic, a new antibiotic is introduced and the pathogen
must start from scratch in building resistance. However, the model implies that pathogens actually e...
Full promise of genomics in disease research yet to be realized
... Certain themes have emerged from the analyses of pathogen
genome sequences and the possibility exists that a "common thread" genetic sequence may be found linking pathogens of wildly different species, says the report. Finding such a "Rosetta Stone" of pathogenesis could ultimately expedite disease control ...
